Product Description
The Model XL Commercial is a quick response sprinkler.
It is a fusible solder link type automatic sprinkler designed
for standard coverage applications. These sprinklers have
demonstrated response time in laboratory tests which is five
to ten times faster than standard response sprinklers.
The quick response feature enables the Model XL Com-
mercial Sprinklers to apply water to a fire much faster than
standard response sprinklers of the same temperature rating.
Modern architectural designs require sprinklers that pro-
vide not only the best fire protection, but also an attractive
appearance. The Model XL Commercial meets both criteria.
The flush style of this sprinkler provides for an aesthetically
pleasing installation by concealing the entire sprinkler oper-
ating parts with the exception of the heat sensing link. Only
when the solder of the sensing link melts does the operating
mechanism release, allowing the deflector to be extended
for distributing the discharging water. The Model XL Com-
mercial has been designed for use in facilities such as office
buildings.
Application and Installation
All Model XL Commercial sprinklers are UL Listed for use
with the following types of fire protection systems: wet, dry,
or preaction. Care must be exercised that orifice size, tem-
perature rating, and sprinkler spacing are in accordance with
this bulletin and the latest published standards of the Na-
tional Fire Protection Association or the approving Authority
Having Jurisdiction. Quick response sprinklers are intended
for standard area coverage and standard water densities as
specified in NFPA 13. Quick response sprinklers and stan-
dard response sprinklers should not be intermixed.

These sprinklers must be installed with a Reliable
Model ZX Sprinkler Wrench. Any other type of wrench
may damage the sprinkler which is designed to allow
wrenching with the shipping cap installed, thereby pro-
viding further protection to the sprinkler. Shipping caps
should be removed only after walls are finished and when
escutcheons are being installed. When Model XL sprin-
klers are ordered, escutcheons and retaining flanges are
included. The Model XL Institutional Escutcheon is the
only escutcheon that can be used with this sprinkler. The
use of any other escutcheon will void all approvals and
negate all warranties. Also, each installed sprinkler must
include an escutcheon.
Use care to avoid damaging the sprinklers before,
during and after installation. Install them according to
Caution Sheet CA-132, and inspect all installed sprin-
klers to insure that they have not been damaged. Re-
place all sprinklers which have any sign of damage.

Maintenance
Model XL Commercial Sprinklers should be inspected and
the sprinkler system maintained in accordance with NFPA
25. Do not clean the sprinklers with soap and water, am-
monia or other cleaning fluids. Remove any sprinkler which
has been painted (other than factory applied) or damaged in
any way. A stock of spare sprinklers must be maintained to
allow quick replacement of damaged or operated sprinklers,
in accordance with NFPA requirements.
